Description

Technical Field

[0001] The utility model relates to the field of sewage treatment equipment, in particular to a filtering and dosing integrated machine for sewage treatment. Background Art

[0002] The use of powdered polyacrylamide inside the sewage tank for sewage treatment mainly utilizes the flocculation effect of polyacrylamide; polyacrylamide is a water-soluble high molecular polymer that can condense suspended matter and colloidal particles in sewage into larger flocs through adsorption, bridging, and cross-linking, thereby accelerating sedimentation and separation;

[0003] Specifically, the flocculation of polyacrylamide can be divided into the following steps:

[0004] Adsorption: The functional groups on the polyacrylamide molecules can interact with the charges on the surface of suspended solids and colloidal particles in the sewage, so that the polyacrylamide molecules are adsorbed on the surface of the particles;

[0005] Bridging: When polyacrylamide molecules are adsorbed on the surface of multiple particles, they form a bridging structure that connects these particles together to form larger flocs;

[0006] Cross-linking: Under certain conditions, cross-linking reactions can occur between polyacrylamide molecules to form a network structure, further enhancing the stability and strength of the flocculent;

[0007] Through the above flocculation effect, polyacrylamide can effectively remove suspended matter and colloidal particles in sewage, improve the clarity and treatment effect of sewage;

[0008] When adding powdered polyacrylamine inside the sewage tank, if the adding speed is too fast, the powdered polyacrylamine will form lumps of different sizes inside the water body, making it impossible for all the powdered polyacrylamine to react quickly with the sewage. Utility Model Content
